For this case we have the following expressions:
a) [tex]1.71 * 10 ^ 3[/tex], in this case we have a positive exponent, therefore we move the decimal point as many times to the right as indicated by the exponent, that is, 3 times. So, we have:
[tex]1.71 * 10 ^ 3 = 1,710[/tex]
b) [tex]8.05 * 10 ^ 5[/tex], in this case we have a positive exponent, therefore we move the decimal point as many times to the right as indicated by the exponent, that is, 5 times. So, we have:
[tex]8.05 * 10 ^ 5 = 805,000[/tex]
c)[tex]2.4 * 10 ^ 4[/tex], in this case we have a positive exponent, therefore we move the decimal point as many times to the right as indicated by the exponent, that is, 4 times. So, we have:
[tex]2.4 * 10 ^ 4 = 24,000[/tex]
d) [tex]8.25 * 10^{-3}[/tex], in this case we have a negative exponent, therefore we move the decimal point as many times to the left as indicated by the exponent, that is, 3 times. So, we have:
[tex]8.25 * 10^{-3} =0.00825[/tex]
e) [tex]7.09 * 10^{-6}[/tex], in this case we have a negative exponent, therefore we move the decimal point as many times to the left as indicated by the exponent, that is, 6 times. So, we have:
[tex]7.09 * 10^{-6} = 0.00000709[/tex]
f) [tex]3.99 * 10 ^ 5[/tex], in this case we have a positive exponent, therefore we move the decimal point as many times to the right as indicated by the exponent, that is, 5 times. So, we have:
[tex]3.99 * 10 ^ 5 = 399,000[/tex]
g) [tex]8 * 10 ^ 7[/tex], in this case we have a positive exponent, therefore we move the decimal point as many times to the right as indicated by the exponent, that is, 7 times. So, we have:
[tex]8 * 10 ^ 7 = 80,000,000[/tex]
h) [tex]1.03 * 10^{-4}[/tex], in this case we have a negative exponent, therefore we move the decimal point as many times to the left as indicated by the exponent, that is, 4 times. So, we have:
[tex]1.03 * 10^{-4}= 0.000103[/tex]
Answer:
The correct options are: b, e, g and h
